Mackpro Posted August 16 Share Posted August 16 P105594 is set when trying to put automatic transmission into gear without pushing brake pedal. P215A64 is when the ABS wheel speeds don’t match the speedometer sensor. The other is possibly low voltage to brake switch, Quote Link to comment Share on other sites More sharing options...
